CAKE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 501,274, dated July 11, 1893.

Application filed April 7, 189? fierial ITO-469,385- (No model.)

a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cake-Machines, of which the following is a specification.

The principal objects of my invention are first, to provide a durable, efficient and comparatively inexpensive machine for shaping or molding a plastic mass into cakes, crackers and the like and depositing the same in or on pans or other receptacles; second, to provide comparatively simple, positive and reliable means for feeding the plastic material into the machine; third, to provide compact mechanism for operating the moving parts of the machine with a positive motion; fourth,

' to provide means for adjusting the feed, while the machine is in operation; and fifth, to provide com partively simple mechanism for feeding the pans or receptacles for the lnolded plastic mass with a differential motion.

My invention consists of a cake machine, comprising a feed-roller provided with pivotal paddles or deliverers having lugs adapted to collide with a projection near the mouth of a supply chamber or hopper to cause the paddles or deliverers to assume an open position for receiving and conveying plastic material therefrom and to be maintained in an open position in the range of the mouth thereof and to a rib, bar or arch located in the lower part of the casing of the feed-roller for rocking the paddles or deliverers into closed position during the discharge tangentially of the plastic material through a throat or outlet into a reservoir, a plunger for controllingthe passage of the plastic material from the reservoir through openings, molds or dies in the base thereof, an endless conveyer and movable table for 1 presenting the pans or other receptacles for the reception of molded plastic material,and mechanism for operating the feed roller plunger, endless conveyer and table.

My invention further consists of a cake machine provided with a feed-roller having a ratchet-Wheel, a positively driven shaft, a rocker-arm operated by said shaft, links pivoted at one of their extremities to the free end of the rocker-arm and provided at their other extremities with pawls operating alterin respect to the fulcrum of the rocker-arm. 7

My invention further consists of the improvements in cake machines hereinafter described and claimed.

The nature, general features and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which- Figure 1, is a view partly in side elevation and partly in section of a cake machine, embodying features of my invention. Fig. 2, is a perspective view of the feed-roller. Fig. 3, is an end view partly in section on the ...line 33, of Fig. 1. Fig. 4, is a detail view of the rocker-arm that serves to impart motion to the pawls that drive the feed-roller; and Fig.

5, is a View illustrating a modified form ofmechanism for operating the rocker-arm.

In the drawings a, is the main-frame of the machine and a, the standards thereof.

b, is an open top housing mounted upon the main-frame a, and provided with a supply chamber or hopper b, a reservoir 6 and a cylindrical casing b interposed between and in communication with the mouth of the supply chamber or hopper b, and the outlet or throat I), of the reservoir 6 c, is a feed-roller provided at its heads or ends with flanges c, and revolubly supported in the casing if, for a purpose to be presently fully described. I

0 are paddles or deliverers pivotally attached at or near their inner edges by means of pintles 0 as illustrated in Fig. 2, to the heads or ends a, of the feed-roller, so that the paddles or deliverers 0 may be rocked in respect to the face of the feed-roller c.

Eachpaddle or deliverer 0 is provided with a lug or pin 0 adapted to travel in a slot b, formed in and extending nearly two-thirds of the entire circumference of the interior wall of the cylindrical casing 19 and adapted to collide with a projection b located near the mouth of the supply chamber or hopper b, in order to rock it into open position for receiving and conveying plastic material around the annular or cylindrical space b t0 the left of the cylindrical casing b asillustrated in Fig.1.

ICO

to prevent them after the deposited material it has been brought into contact therewith and inoperative and useless.

the paddles thrown open, from assuming a reverse or closed position in their travel to the left until the material has been thrown off tangentially through the throat b into the reservoir b when the paddles again contact with a similar arch or device b ,beneath the feed-roller c, and the paddles or deliverers again assume a closed position in their travel to the right in the cylindrical casing o as illustrated in Fig. 1. The space between the feed-roller and the casing to the left in its travel therein, is such as that the paddles or deliverers are always maintained in an open position so as to convey the deposited material therethrough and discharge the same tangentially through the throat 11, into the reservoir b while the distance between the feed-roller and the casing to the right is such as that the paddles will be maintained in a closed position in contact with the periphery.

Hitherto it has been suggested to employ a feed-drum having wings connected in pairs and afforded a range of play in radially disposed slots therein, but in practice the plastic material engaged owing to its nature between such wings and the walls of the radially disposed slots and thus became wedged in the former in such manner as that they were prevented from moving or performing theirfunctions, whereby the feed-drum was rendered The hereinabove described paddles or deliverers in effect are hinged to the face of the feed-roller c, and consequently cannot become wedged by the plastic material in any such manner as above explained, and in practice they have proven most satisfactory.

cl, are plungers penetrating the top wall of the reservoir b and adapted to control the passage of the plastic material from the reservoir b through openings, molds or dies b, in the bottom wall thereof. In the present instance these dies, molds or openings b, are provided with flanges Z9 cut or otherwise formed in a plate detachably connected with the base or wall of the reservoir by means of bolts I2 so that the plate may be removed and replaced by another plate having differently shaped dies, molds or openings.

6, is an endless conveyer guided by means of sprocketwheels e and e journaled to the main-frame a, and provided with vertical pins 6 adapted to engage eyes attached to pans or other receptacles.

movement in ways in the main-frame a, and adapted to lift the upper side of the endless conveyer in order to bring the pans or other receptacles into range of the depending flanges b of the openings or molds 1).

g, is a main-shaft positively driven through the instrumentality of gear-wheels g and g by a driving shaft h, having tight and loose pulleys h and 72 to which power is applied.

'6, is a rocker-arm centrally pivoted to the main-frame a, and having one of its extremitiesprovided with ways 11', for the accommodation of a block journaled to a crank-pin projecting from a disk 4?, keyed or otherwise secured to the main-shaft g, and located outside of the main-frame a. However, if preferred the ways t" and their complemental pivot block may be dispensed with. In such case the end of the rocker-arm z, is connected with the crank-pin of the disk 1?, by means of a connecting-rod as shown in Fig. 5. The free end of this rocker-arm t', is also provided with ways for the accommodation of a block to which the lower extremities of the links or bars '5 and i are pivotally'attached. The upper extremities of these links or bars, are provided with pawls 2' and '5 operating alternately upon the teeth of a ratchet-Wheel 2' keyed to the axis of the feed-ro1lerc, in order to effect the rotation of the latter.

3, are pivotal-arms j on rnaled at one of their extremities to the axis of the feed-roller o, and connected at their opposite extremities with the bars or links 2' and 2' in order to prevent accidental displacement of and to guide the latter.

2'" is a set-screw provided with a handwheel and adapted to afford means for adjusting the block 'i ,in respect to the fulcrum of the rocker-arm '5, whereby the throw of the pawls t and 2' may be adjusted, while the machine is in operation, in order to increase or diminish the velocity of movement of the feed-roller o, and consequently the feed of the plastic material.

j, are cams or eccentrics keyed or otherwise secured to the shaft g, and provided with faces 3'', engaging rollers f, depending from the table f, and with grooves 3' engaging rollers attached to the lower ends of the rods d, having their upper ends attached to abar d penetrating eyes projecting upward from the plungers d, so that the cams or eccentrics operate first to lift the table f, and depress the plungers d, and then to depress the tablef, and lift the plnngers d.

The sprocket-wheel e, is provided with a ratchet-wheel e, and with a pivotal-arm 6 having a pawl 6 adapted to mesh with the ratchet-wheel 6 This arm a is rocked or oscillated by means of a link having its respective extremities connected with posts afforded a' range of adjustment in radial slots in the arm 6 and gear-wheel g whereby the throwof the link, and consequently the range j of movement of the pawl e, and speed of the f, is a table afforded a range of vertical endless conveyer may be increased ordiminlshed. The pawl e", and ratchet-wheel c serve to drive the endless conveyer c, at a comparatively low rate of speed.

70, is an arm pivotally mounted on the axis of the sprocket-wheel e, and provided with a pawl 10', adapted to mesh with a single space out or otherwise formed in a ratchet-wheel I0 is'a link connected at its respective extremities withposts afforded a range of adjustment in radially disposed slots cut or otherwise formed in the arm 70, and gear-wheel g, in order to permit of the regulation of the throw of the pawl 70', and consequently of the travel of the endless conveyer e. The pawl is, and ratchet-wheel k serve to drive the conveyer e, for a distance corresponding to the length of the pan or receptacle at a comparatively high rate of speed, whereby the pans or receptacles are brought rapidly beneath the die or openings b, in order to receive the molded material, and are also rapidly withdrawn therefrom after being filled. In this connectionv it may be remarked, that while the pans are being filled they are fed slowly by means of the pawl 6 in order to cause thedeposits of molded material to be distributed evenly up and throughout the pan or receptacle, so that a dilferential motion is imparted to the pans or other receptacles by means of the pawls k and e, and their accessories.

The mode of operation of the hereinbefore described cake machine, is as fo1lows:-Plastic material, as dough or similar material, is deposited in the supply chamberor hopper b, and is conducted around the left hand side of the feed-roller c, by means of the paddles 0 which for this purpose are rocked into open position by means of the pins 0 and projection 17 and which are subsequently rocked into closed position by means of the rib or arch 12 upon and during the dischargetangentially of the plastic material through the outlet or throat b into the reservoir b The pawls t and i serve to rotate the feed-roller c, and the speed of the latter and consequently the rate at which the plastic material is fed into the reservoir b may be increased or diminished .bymeans of the setscrew 2' while the machine is in operation, as has been hereinbefore explained. The endless conveyer e, moving rapidly under theinfluence of the pawl k, causes a pan or other receptacle to be brought beneath the molds, dies or openings b whereupon the camsj, first lift the table f, and depress the plungers cl, and then lift the plungers d, and depress thetable f. During the elevation of the table and the depression of the plungers, the latter cause the plastic material to be compressed in the reservoir 19*, with the result that it is forced through the openings or dies 6, in its required molded state and deposited upon the pan or other receptacle. As the pan is descending the plungers ascend, thus relieving the pressure against theplastie mate rial in the reservoir b so that the flow thereof through the openings or dies b, is checked. The pan is then fed slowly forward by the pawl 6 until the previously deposited material is removed from beneath the openings or dies o whereupon the hereinabove explained operation isrepeated and the molded plastic material is deposited upon the remaining portions of the pan or other receptacle. As soon as thepan or receptacle for the said molded material is filled, it is fed rapidly by the pawl is, toward the right hand end of the machine, and may then be removed to bake or otherwise treat the plastic material deposited thereon.
